To study how the variance relates to uncertainty, we perform the following experiment:
We introduce unnatural (read: not present in the training data) structures into the image by overlaying the cameraman image and an example of the grid texture from the Describable Textures Dataset [1]} on a reference scan.
Subsequently, we approximate the variance of a few-view reconstruction problem using \( n_\theta = {20} \)  views by Langevin sampling.
